Application tiled January 18, 1911. Serial No. 603,374.

T0 all t may concern:

Be it known that I, LnvrN Gnssronn .Y HANDY, residing at Rutherford,Bergen is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and to use thesame, reference being had to the accompanying drawings, which illustratethe preferred form of the invention, though it is to be understood thatthe invention is not limited to the exact details of construction shownand described, as it is obvious that various modifications thereof willoccur to persons skilled in the art.

said drawings: Figure 1 is a longitudinal sectional view of a portion ofa car illustrating my invention applied thereto, said section beingtaken approximately on line 11 of Fig. 2. Fig. 2 is a transversesectional View through a portion o.c a car, said section being taken onthe plane indicated by line 22 of Fig. 1, and looking in the directionof the arrow. Fig. 3 is a detail view of the crank-arm.

This invention relates to mechanism for closingthe doors of hopperbottom cars.

The object of the invention is to provide mechanism which will furnishpositive locking means for said doors when in their closed positionwithout the4 use of the customary pawl and ratchet mechanism.

A `:further object is to provide an increasing leverage upon the lockingarm of the mechanism as t-he door is swung to its final closed position.v

A further object is to provide, in combination with the above, means formaintaining the door practically rigid in its fully open position.

jecting link-arm 6. At its free end said link-arm carries a wrist-pin 7.

Journaled in a suitable bearing as 8 formed 1n one of the brackets 4 andextending to one adjacent side of the oar, `or entirely across the carif desired, is an operating shaft 9. A journal bearin llOis fixed to theunder sideof one or eac ',ofithe adjacent side girders for supportingthe outer end or ends 0f said shaft.

The shaft 9 extends through and is supported in the bearing 8 and.carries a radial lever, or crank-arm 12, which armA is slotted as at 13.The wrist-pin Tprojects into said slot and has free ,sliding movementtherein. A suitable head as 14 is formed upon the end of the wrist-pin,outside the slot 13, to prevent disclocatlon of the parts.

The. door actuating link 15 is pivotally connected, as at l15", to thelower or free -edges of the doors 16, it being understood that there visa door 16 foreach of the` hopper chutes 3 and that the Said doors arepivoted along their-upper edges as at 17,

yas 1s common in the art.

The operating shaft 9 is spaced slightly `below and somewhat to theright of the `shaft 5, Fig. 1.

Thefslot 13 in said crankarm is arranged practically radial with theshaft 9, but is preferably disposed so that a lineA along the centerthereof will pass slightly to one side of the said shaft 9, so

variable relative movement of the wrist-pin as to the crank-arm. As thecrank-arm 12 is swung t0 Close the door, the wrist-pin 7 will movegradually toward the inner end ofthe slot 13 and nearer the shaft 9,thus gradually increasing the available leverage of the crank-arm uponthe wrist-pin until the maximum leverage is reached when the doors arefully closed and the door operating link is in engagement with the uppersurface of the shaft 5.

A pocket as 13 is formed at the extreme inner end of the slot 13 and isadapted to engage the wrist-pin after said wrist-pin has reached itsfinal forward or locked position and thus retaining the wrist-pinagainst possible return. It will be noted that the outertherefromthrough the center of the shaft 9,`

is preferablyl arranged at a slight incline relative to said line as isgapliieally illustrated in Fig. 3 ot the drawings, and that. thus SaidWall will readil)v disengage. itself from the wrist-pin when theoperating sliatt is rotated for opening the doors. 'When the wrist-pinis in the pocket 13, as illustrated in Fig. 1. said wall serves toprevent moreinent. ot the wrist-pin and hence of the doors. the entiredead weight ot' the tree end of the Crank-arm heing` disposed tomaintain the ei'igageiiieiit. lVitli the wrist-pin thusl positively heldagainst movement all neeessity for the eiistoinaiw' pawl and ratchetmechanism oliviated.

The renter of the wrisi-pin T is in aiineinent with thel centerotI the sha l't and the pivot pin l. or i'ireteral'ily slightly helow`said alinenient` so that the door is positively loeked in its closedposition. rl`he severe jolting to whieh the parts are suijeet. in usewould. liowiwer, were it'iiot tor the engageineizi otl the wrist- Vpinwith the outer wall of the poeket lil, Cause the rear end ot the dooraetiiating link 15 and the link-arm (3 to rise and so permit the door toopen. The engagement ot the wrist-pin within the poeket 13 positivelyprevents movement ol' the wrist-pin and tliiis obviously no furtherretaining means is required. As the operating shaft is rotated and. theerank-arm swung tor opening the door. the Qoeket- 121, will lii'st helit'ted trom .its engagement with the wrist-pin and said wrist-pin willhe tree to travel along the Slot lil, As the operating' sliat't isfurther tlirned, the wrist-pin will more townard the outer end ot saidslot and` finally, as the parts reach the position illustrated hy theheavy dotted lines, the liody ot' the ei'ankA arni strikes the shalt 5so that l'nitliei' rotation of said crank-arm pi'ewnted. and the freeend ofthe door actuating link t5 is supported iii such manner as tomaintain the, door piartieally rigid.

ln closing and locking the door the shaft.- f) is rotated in a reversedirection and diii'- ingv this rotation the piii 7 will more toward theinner end of the slot'.y thatI is, toward the operatii'igshaft or Centeroli torre, thus gradually inereasing the degree of leverage upon thedoor actuating link. lt .should be noted in this eonneetion that. thelink-arm t' at this time. aside troni itsl 'imetioii ot' transmittingthe \i eight olt the doors to the shaft` i?. sem-er; to guide thewristpiii 7 and the t'ree end ot' the door artuating link ronrentiieallyaround the shaft Tand eonseduently.
